Series 6A Operation & Maintenance – field Connections
6A O & M : 6
fIelD WIrInG
Each S6A is provided with two conduit entries for power/incom-
ing analog signal of the main unit and any optional modules.
Please refer to the wiring diagrams referenced in this docu-
ment when connecting the positioner and any optional modules.
It is essential to install the optional modules before connect-
ing the positioner electrically. Refer to the following “Technical
Description” portion of this manual for relevant power distribu-
tion sizing information when installing a S6A positioner and its
optional modules.
Safety Notes:
• Local regulations regarding hazardous environments must be
followed when installing this device in a hazardous location.
• The conduit connections must be properly sealed to maintain
the weatherproof integrity of the actuator enclosure.
• Never connect the current input (terminals 6 and 7 as shown
on the diagrams to the right) to a power source; the positioner
will probably be destroyed in that case. Always use a current
source with a maximum output current of I = 20 mA.
• To maintain auxiliary power, the input current must be a min-
imum of 3.6 mA.
Note: The plastic enclosure is metallized from inside to
increase the electromagnetic compatibility (EMC) with
respect to high-frequency radiation. The shield is connected
to the threaded bush shown in Figure 1 such that it is elec-
trically conductive. This protection is effective only if you
connect at least one of the bushes to the grounded control
valves through electrically conductive (bare) attachments.
